Description

See strex::match_arg().

Usage

match_arg(arg, choices, index = FALSE, several_ok = FALSE,
  ignore_case = FALSE)

Arguments

arg

A character vector (of length one unless several_ok = TRUE).

choices

A character vector of candidate values.

index

Return the index of the match rather than the match itself? Default no.

several_ok
